Sections:	Current Protocols: 9.2.6 Nodal Protocols: 9.5.8
Description:	Sets a lower limit to the number IDR meters within a Meter Reading Entity (MRE) that would be considered when determining whether the IDR threshold requirement is met or not for true-up settlement.
Reason:	Protocols require that ERCOT receive IDR data for 99% of all IDRs ERCOT wide and 90% from Each Meter Reading Entity (MRE). This IDR threshold requirement was written with the assumption that MREs would be responsible for hundreds if not thousands of meters. There are now MREs with very few IDR meters. ERCOT has come close to suspending publication of true-up settlements due to lack of meter data for a single IDR meter. This PRR prevents the suspension of true-up settlement statements for lack of IDR meter data from small MREs responsible for less than 20 IDR meters.
